1.3 Device Information

The BQ25756EVM evaluation module (EVM) is an evaluation system for the BQ25756 IC. The BQ25756 IC is a buck-boost battery charge controller with a wide input range of 4.2V - 70V, a wide output voltage range of up to 70V, and bi-directional capabilities.

The device offers high-efficiency battery charging over a wide voltage range with output CC-CV control. The device integrates all the loop compensation for the buck-boost converter, thereby providing a high density method with ease of use.

Besides the I2C host-controlled charging mode, the device also supports programmable hardware limits. Input and output current regulation targets can be set with single resistor on the IIN and IOUT pins, respectively.
